Incorporation of beam splitters
Optical unlock
By moving the box in a limited area, the target is illuminated.
The number of beams required for each target is different, ranging from 1 to 3.
There are many chests that cannot be moved, and there are matching chests that are portals.

First look at the position of the movable box in the upper left corner. If it is placed in the second row and third column, there is no solution:
So this first box can't be placed in the second row, and then you can get the answer by pushing it step by step.

Total number of beams theory
The number of beams required by the target <= the total number of beams <= the number of light sources + the number of beam splitters
The beam splitter is a device that injects a beam of light and can emit two beams of light.
The general level is the number of beams required by the target = the number of light sources + the number of beam splitters.
Such as a state in 2-6:
There is only one beam left to illuminate all, and there is also a beam splitter that is not used, so there is no wasted beam.
2-7
There is a three beam splitter, which can emit three beams of light when one beam is injected.
The theory of the total number of beams is modified as the number of beams required by the target <= the total number of beams <= the number of light sources + the number of two beam splitters + the number of three beam splitters * 2

Incorporation of beam splitters
Two immovable beam splitters are combined into a large beam splitter with four ports, any one port injects light and emits three beams.
